Not yet but that’s the eventual goal once their device database is sufficiently large and robust enough.

As more of the same models of devices in different homes gets added to the database, its specific device signature becomes more accurate.

That’s why there’s an entire entry on helping Sense by renaming devices: [quote]What does the data science team do with the new information? They make use of this annotated data, among other tools, to design appliance models. As is typical with machine learning and statistical algorithms, the more transcribed data available, the better the performance. By renaming an unnamed device appropriately, you help grow the Sense appliance corpus, which feeds into our training algorithms. This helps us improve the detection of not only your device, but also similar devices used by others. In this way, the whole community of Sense users is contributing to the improvement of Sense’s device detection![/quote]
